Queries :: Data Validation Of A Field In Existing Table
Aug 13, 2015
I'm trying to write a query that will validate a field in an existing table. I want the query to show where any of the 412,000 records fail this strict validation:
AAnnnnnnA
...where A is any letter A-Z and n is a digit 0-9
Clearly I can use the LEN function to check for invalid lengths (anything <>9), but I'm looking for a simple neat expression I can use that will check the format. Does an existing function already exist before I resort to writing my own function in VBA (again)?

-Microsoft Access 2010
-Existing Access Database contains tables with 1-2 million records
I would like to add a field[dol] to an existing table[rei]. I need this new field[rei].[dol] to be populated with existing data from another table[main] based on the associated field[main].[account1] or [main].[account2] or [main].[account3].
Table1[main]
...account1
...account2
...account3
...dol
[code]...
In the [main] table. There is always data in [dol]. But there is NOT always data in the [account] fields. Sometimes there is multiple account numbers per [dol] but not always.
Customers will ALWAYS have at least 1 [account] number and [dol]. Some will have multiple [account] numbers and [dol]. Sometimes these [account] numbers are the same in multiple fields[account1] [account2] [account3].I just need to do a lookup or something to find the [account#] and pull in its [dol] from the [main] table and populate it in [rei].[dol].

I have a form (frmCompany) which has two combo boxes (cmbCompany and cmbCity) which is used to add field data into a table (tblCompany). The Company field is the only required field the other is optional.
In some cases I may wish to add a City, at a later date, to an existing Company using frmCompany. I now select the company from the cmbCompany combo box then add the city to cmbCity. The problem is that when I close the form I get two companies in the table with same name, one has a city and one does not.
How can I add a new City to an existing Company, using the form, without adding a new Company?

I am working on a form that registers new training attendees. One of the fields in my form asks for dealer number.
I have a separate table where all the dealer information is stored. One of the fields is a Customer Number field
I want to ensure that entries in the Dealer Number textbox on my New Registration form matches a valid Customer Number in the Dealer Database Table
I would like this verification to occur either upon a Click event with a button or on an After Update event.

I've two tables, QA (Quality Assurance) and Instruments. I'm using form to add data to QA.
There's a field in QA, named InstrumentUsed. The criteria is that InstrmentUsed should only accept value when 'status' field in Instruments table shows 'working'. If status is 'faulty' or 'need repair', it should pop up the related error message and cursor stays on the same field.
I've not starting learning VBA yet, so I'm trying to make use of Macro's.
How to use data from another table as a validation criteria for a field in form?
Pops up a MessageBox and stays on the same field, on the form, unless error is resolved?

I have a database that I import data from an excel spreadsheet into multiple times daily. The table that this data is imported into has several key fields that if the data already exisits in the table, and I attempt to import data that is the same except for one or more of the key fields is different. At this time the database it creates a different record. I am trying to get the database to overwrite the data in the database.

I have a TSQL procedure written which validates if a record already exists. It returns a 1 or a 0 depending on if it finds a valid record based off a supplied paramater (an application ID in this case, stored as Text(14)).
I want to accomplish the same thing but in a standalone Access DB where I don't have access to SQL stored procedures. Basically, here's what I have:
frmInputNew contains a text box txACAPS. When a user enters in a number in the txtACAPS field, and tabs out, I want an event to run which checks that string against a table. If the string exists within a field in the table, I want to break out and open a new form (which will be a dialog box). If it doesn't exist in the table, I want to end the code and let the user continue entering in data.
I'm not entirely sure how to check a table for a value via VB and return a flag that I can form an IF/ELSE statement from. Any help would be appreciated.

Hi.
I have a table with a NAME field and a GENDER field.
How would I code a query so that if the gender is MALE than MR. would be added to the front of the existing data in the NAME field? MRS. if gender is FEMALE?
i.e., the result would be MR. SMITH, MR. JONES, MRS. CARSON...

I have one DB that is used for creating/storing customer ID's, and another DB that is used for creating/storing job information for customers.I have linked the table from the customer DB to the job DB.
There is a table in the job database that holds customer name and ID, and some VBA that generates unique job codes.
Is it possible to have the data from the linked table automatically update into the existing table?

I am working from an existing database which is just two table. The main table has a massive amount of redundancy and duplication and needs splitting into, at first glance, 5 tables.
After I have run my various make table queries and added a Primary Key and FK field to the new tables how do I populate the FK with the Parent PK.
I thought I could simply add all the fields from the new table and then create an adhoc join in an update query to populate the PK to the FK. When I do this however I get "You are about to update 0 records"
I have tried the table analyzer but it doesn't give the correct options to split the table the way I need.

I am trying to add a new email field to my existing database of 900 employees. I have imported an excel worksheet of email addresses into a new table that has lastname, firstname, employee#, email. The primary key on the new table is email. The primary key on the employee table is employee#, and there is a new field titled email.
The email field in both tables are text fields. In running an append query, it either adds 900 to 27000 additional fields of email only or it says cannot complete because of key code violations. On the join properties I have clicked on #3 all records from source to only equal fields of destination.

Please bear with me, first post, trying to get to grips with Access for work!
We (a primary school) had a "bespoke" database set up using MS Access by someone who has long left the area and now we need to make changes and I, as the most computer literate person on site, have been volunteered to make these changes.
My level is beginner (for now) and my first job is to add some new options to a "Titles" table, four columns, six records. Column1 = ID#, Column2 = Male Titles, Column3 = Female Titles, whilst Column4 seems to hold items from Columns 2 & 3.
If I add a futher option, I get the error "Can't perform cascading operation: Entry must be one of the Titles as featured in the drop-down box or in the Titles table.
Now, as far as I can tell, I HAVE added the new option to the Titles table, and they DO show in the drop down box in the main spreadsheet display, BUT the error comes back as soon as I try to confirm the new title.
Any ideas please?

I have a query in design view that consists of two calculated fields at the moment. One of the calculated fields is supposed to add one year onto a value from another date/time field called "Last_Date."
The expression I've written in the "Field:" box in Query design view is
Expr 2: DateAdd('yyyy',1,[Last_Date])
When I try to run the Query it doesn't work! Access just prompts me to enter a parameter value for Last_Date.

I have a field called uniqueID which I would like to update based on 2 other fields that are already populated in my recordset (from running previous queries). I heard it is not possible to do an Update Select like shown below.
select max(uniqueID) from myTable where a = "value of field a from first record in record set" and b = "value of field b from first record in record set"
If it is true that I cannot do an Update Select then I am trying to do something in VBA. How can I Loop each row in the record set and store the values from fields a and b. I would obviously then need to pass those values into the sql above and store the result in a variable. I would then do a straight update to put the value of uniqueID into myTable.

I have a query called "Stock" containing field like (Item, Description, product_qty)
Another is a table called "Sales" with fields like (Sales_ID, Item, Sales_description, sales_Qty, date_Of_Sale) Item field on sales is a foreign key.
Now what i want is how can i make when the user enters new record, in field "Sales_Qty" the data entered here to be less than product_Qty.
NB; this is because you can not sell more than what you have.

Say I have a table [tbl1] and a recordset [rst1].
The fields in both items are the same. Now, how do I copy/dump/inject (what's the correct term?) the data from the recordset into the table?

i'm a Access novice. I have tables with existing data in numerical form, and would like to know how I can use Queries or VBA code to update these values into a new format in a new table. for example the original data might be of race type:
1 - caucasian
2 - african american
3 - hispanic 1
4 - hispanic 2
5 - hispanic 3
6 - other
and i want to regroup these into less types, eg:
1 - caucasian
2 - african american
3 - hispanic
4 - other
how can i achieve this in Access? i know how i can do this conceptually with "if" and "case" statements, but I have no idea how i can do this in Access. I don't want to mess with the original data, so please help with CODE or QUERY examples.
thanks!!

what is the best way to import the data from the XML file into an access database table. The database I am working with has one large main table where all of the main record data is stored. There is a somewhat complex string of queries and reports based off this table that I am concerned about preserving. The problem is that the XML file is not structured in the same way the table is. The headings are named different, aren't in the same order, etc. I cannot use the import method and simply append it to the main table.After much searching around I have found two options:
1) Use the built in XML import method that access provides to create a secondary table. Then find a way to take data from individual fields in the second table and map and insert it into a new record in the main table.I already have the import part of this option working. The only part I can't seem to understand is how to take data from the second table and get it into a new record in the main table under the correct headings
2) Read the data from the XML file all at once and then map and insert it into the main table.I have not attempted this yet. I was having a hard time understanding how to retrieve the data from the XML file in the first place.
So.. which would be better/easiest to automate (most likely via button click on a form)? I only have a small understanding of VBA and even less understanding of anything XML.

File sharing lock count exceeded. Increase MaxLocksPerFile registry entry.
If I answer yes I get an error that the new field was not added. Is there any way to add a key foield to an existing database?

I have an "order details" table that needs to populate a field called "Voucher" with data from another table called "codes". The "codes" table also has a true/false field called "allocated" because once allocated the code cannot be re-used.
I am trying to work out how to automatically allocate the next unallocated code in the "codes" table to each record in the "order details" table when that order details record has a DiscountID of "92".
Order Details Table Fields and conditions/criteria:
ID - primary key
DiscountID - only when the DiscountID = 92
Voucher - only populated when Discount ID = 92
Codes table Fields and conditions/criteria:
ID - primary key
code = text field with a code like "einstein01", "einstein02"
Allocated = False
Is there a way to put the next available code into the order details record then mark that code as allocated in the codes table. Then, move on to the next order details record that has a discountID = 92, input the next unallocated code and mark that code etc. etc.
Ideally, I would like to do this to happen via an event when the Order forms button "Close" is clicked.

I have a form with subform (datasheet) .
On my subform i have one field which shows the
productId ( which is filtered from combo boxes on main form) .
productId contains two columns
1 bound column(id) ( hidden with width 0 )
2 column (desription) ( shown with width 2 )
Now after entering the data when i come back to the form again . It hides the data from the productId field on subform , because data in combo box (on main form) doesn't match. Although the row is showing up , only the text in field (productId) is hidden.
Now when i change data in combo box on main form to match the ProductId , then the productId field text shows again. after changing combo box it hides . What i need is the existing data should not hide when i change the combo box selection.
see pic 1 where product matches and pic 2 where not. please note i am using master child relationship on the form/subform.

I'm trying to add a combo box field to an existing table and form. I added the new field to my existing table and set it up as an combo box added my row sources. Then added the new field to an existing form and now am getting a error stating "The record source "Table name and added field here" specified on this form or report does not exist. When I just make the new field a text box instead of combo box it works just fine.
